how do you delete a yahoo account?

Make sure you have signed out of any account you wish to keep and then click here:

https://edit.yahoo.com/config/delete_user

You will not be able to access the account immediately but the actual delete will take 90 days.

I recommend you read the following warnings from Yahoo:

When you terminate your account you will lose access to your Yahoo! ID, Yahoo! Mail, and profile names. They will also delete your account data and settings across the Yahoo! network. This includes any contents in:

₪ Yahoo! Mail

₪ Yahoo! Address Book

₪ Flickr

₪ Yahoo! HotJobs

₪ GeoCities

₪ My Yahoo!

₪ Yahoo! Groups

₪ Finance Portfolio

₪ Yahoo! Answers - profile only - Q&A remain

and any other area of Yahoo! that can only be accessed with your Yahoo! ID and password.

₪ ɦəlʞɹɐq ₪

First, make very sure that is what you want to do, if you delete the account you can never get it back, or use that ID name, either.

Any other yahoo programs associated with your mail account will also be deleted.

If you are sure:

Click on the help at the upper right corner of the screen from the account you want to delete.

Help /Account and password /Your Account Info / How can I delete my account

visit Account Deletion page you will have something to read and then you can confirm you deletion
